Yuuka’s unique work takes learning and noticing things from everyday life, history, and culture, and transforms it into buttons. She expresses herself through the “button brand” which is located on the boundary between design and art. She also works for button manufacturers and apparel brands, and also runs workshops on the creation of buttons, and other things.
